Speed Compensation in Hydraulic Wind Turbine Control
2018 Global Fluid Power Society PhD Symposium (GFPS), 2018The combination of hydraulic drivetrains and wind turbines impose control challenges due to their inherent dynamic behaviour. At the same time, the increase in system performance due to controller improvements causes a considerable impact on the turbine’s performance. In such wind turbines, the system is controlled through pressure.

Closed Hydraulic System for a Wind Turbine
Russian Engineering Research, 2021An algorithm is proposed for calculating a closed hydraulic system consisting of a pump and a hydraulic motor. As an example, the hydraulic system of a wind turbine is considered. The calculation is based on the method used for the hydraulic system of mobile machines. The basic characteristics of the system components are analyzed.

Hydraulic Drive Trains in Wind Turbines for Rapidly Changing Strong Winds
ASME/BATH 2023 Symposium on Fluid Power and Motion Control, 2023Abstract Wind energy is among the most important technologies for reducing our carbon footprint in the atmosphere. An analysis of the wind energy market over the last years shows a favor for wind turbine technology with a rather low nominal speed resulting in a frequent down-regulation or limitation of the harvested wind power by the ...
